disk.

,the meantime. movement of the disk withdraws the dog from engagement with theinternal rack, the 'pin""45-pe rmitting only a limited further of said clutch. The driven member of the clutchcompriscs a disk 33, the periphery of 'which is formed with ratchet teeth 34 at two diagonally opposite points upon its edge for cooperation with a pawl 35 which is maintained in contact with said disk by a spring 36 for a purpose which will resently appear-J Upon the face of said disk ad acent the driving member of said clutch but concentric to said disk a dog 37 1S pivoted 'at 38 and normally retained in the retracted position shown'in Fig. 5 by a sprln'g 39 inte'rfposed between a stud40 on the short end ofsaid dog and a. stop or lug '41 on said Thedog 37-is provided with a wear plate 42, 'the an'gleor corner 43 of which is adapted when the dog is shifted, as will presently appear, to engage the internal 'serration on the flange of the driven clutch oted to the frame of the machine adjacent thefclu tch and its nose ordinarily extends into the path of the arms 46 46,

being held in position to engage the notched "ends 46*, 46 of said arms by spring 36 which, as shown in Fig. 4, connects the pawl 35 heretofore described, with said latch 49.

A powerful tension spring 51 connects that arm 46 which carries the pin 45 with a lug 52 on disk v i Latch 49 is normally in engagement with oneof the arms 46*. When it is desired to throw :the clutch members into engage- .mentfth e latch49is drawn out of engagementwith arm 46. as, for example, by

means of acord'53 which extends to a position convenient to the operator. When the latch is withdrawn'the-spring 51, being superior in power .to the spring 39, shifts arms 46*inthe-direction of-the arrow at thereb through pin'45 'thereonearrying the dog 3 againstthe force of the spring 39 into engagement with the internal rack 32. When this happens the parts of the clutch revolve 'toge'ther i 1ntil the other arm 46 comes in contact with'the latch 49 if the latter has been allowed to return to normal positionin Thereupon the continued movement of said dog. The disk 33 is finally arrested because the parts yust reforred to held stationary and the pawl engaging one ofthe series of ratchet teeth 34 prevents backward movement of the disk,

and thus maintains the dog 37 out of enagement with its rack. The driven side of tie clutch is thus held from further movementuntil the latch 49 is again withdrawn. Because of the provision of two diametrically opposite arms 46 which alternately -engage the latch 49, the driven clutch member makes a half revolution every time it is released.

The driven clutch member is rigidly secured to or mounted upon the sleeve 28 to which reference has been made, which carries at its other end a cam plate 54 which has the function of lowering the land wheel and front furrow Wheel relatively'to the frame 'of'the plowat each alternate half revolution of said cam plate. The connections by wh ch this operation is accomplished are shown in Figs. 1, 2 and 3. I have heretofore referred to the fact that the land wheel and front furrow wheel are journaled respectively upon the free ends of arms at tached to the plow frame and which may be swung about their journals independently in order to raise and lower said wheels. The shaft 55 is journaled on that side of the frame which is adjacent the land wheel and is formed or provided with arms 56,

57 at its respective opposite ends, the former of which is connected by a link 58 with arm 21,- (see Figs. 1 and 2). The other arm 57 of said shaft extends at an angle to said shaft and to arm 56, and is pivoted between side bars 59, 59 which extend rearwardly therefrom and over the sleeve 28 carrying the cam plate. Each of said bars 59 carries a cheek plate 60, which cheeks extend below said bar as at 61 (Fig. 3) forming an abutment, which is engaged by a roller 62 upon said cam plate. The cam plate 54 is so arranged upon the sleeve with reference to the driven member of the clutch that in one of the two positions of the driven member the roller 62 is in its forward extreme position as shown-in full lines in Fig. 3, and in the other position of said driven clutch member the roller is at the other extreme position, as shown in dotted lines in said figure. The cam moves in the direction of the arrow 1 in Fig. 3,- and it will be apparent that as it moves from the dotted line position to the full line posi tion it will carry the structure comprising the cheek plate 6]. and side bars 59 forwardly to the position shown in Fig. 3, thus rocking the shaft 55 through its arm 57 and through arm 56 and link 58, swingingthe land wheel to its lowered position with respect to the frame of the plow. At the same time that the land wheel is lowered the front furrow wheel is also lowered, the arm 17 carrying the said furrow wheel being connected by a link 63 with an arm 64 upon a shaft 65, which is mounted transversely of the plow beneath the beam 7 thereof.

The other end of the shaft 65 carries an'arm MMAQB 66 which at its outer end is formed with a portion 67 which, extends into the path of arm 57 to which reference has heretofome been made. Preferably :the arms on shai'zts .5 :55 and are termed integral itherewith by bending the eylimdnica'l baars cfirom which said shaztts are formed at suitable :points in suitable directions. It will :now be seen that when :the ream plate forces the 'parwllel 55 engages the .end 67 of :the :anm upon the shaft 65, land -:fiorees the latter downward-1y, end this motion is transmitted to the arm :17 carrying the trout furrow wheel which is therefore flowered at the same \time with the land wheel, ithouglh ath-e relative amounts of nioveinent of @the two Wheels may be varied in thedesigning of the device. With the parts in esthe position just described, and as shown in cfull lines in Figs. 1, 2 and 3, when itheila'tch 49 is wagajinatripped the succeeding hal f revolution of the driven member of the clutch =cairries the roller 62 away from the icheek pieces :60, the downward movement of the side bars being limited by their contact VWlllllit'llBBlQBNG 28. This ileaves :the arms carrying :the land wheel rand furrow wheel respectively tree to swing upward, though the extent of :this upward movement is limited as hereinafter idescribed. With the dendiand furrow wheels in (the position shown, :the IPlLONV :bottoms are carried free from theiground, but when ithe roller Jon lzlllle cam :ploete ;-no longer holds the ports in @the iPQSllilOll shown in Fig. 3, the plow hottomsdrop to rthe ground and are in :position to 16111381 'the soil. The extent of the depth of penetration, however, is limited by ad ustable steps which engage :the arms '40 56 :and 764 respectively. "Elihe stop 6.9 for :the-canm which :regulatesxthe position of the ilend WllEBl, isvcnnried "by a hand lever 70 pivoted at .71 upon the *treme .and chevring .o- :pewl ,7 Qmngagirng 1811 .Aarcuate :raek 73 *45 luponetherfimme.

bars diorwamdly :the 1mm 5!? upon the shaft The rear :f-urrow wheel 79 is provided with an independent adjustment which is operated entirely by hand.- Said wheel is cerried by an arm 80 which is bent as shown and journaled in a sleeve 81 iormi-ng apart of a casting which is pivoted at '82 to an a-uxiliary beam :83 bolted \to beam 8 at 84, and held in position by a pair of diagonal struts "-85, 86. The pivoted casting is formed with an upturned arm 87, which at its upper end is connected by a brace '88 with said sleeve .81, and said arm is connected by a link 89 with a hand lever 96 for adjusting vthe position of said casting, and consequently of the rear furrow wheel. A pawl 91 on the hand lever engages an avcuate rack 92 for {locking the parts in adjusted position. The plow is designed particularly for use in conneotion with a mechanical tractor e11d,com prises or [is provided with a hitch consisting-eta transverse bar 95 connected by links '94: to :trame extensions 95 upon the respective beams, the transverse bar'or member being provided with a series of holes for adjusting the connection. The transverse bar is extended on the durrow side as eat 96, Where it is provided with a link 97 for attachment as at =98 to :the rear bar-of .a treetor; a diagonal brace 99, which is adjustable by means of --a series of perforations 100, holds the lin'k 97 in "proper relation to lihe draw bar.

W'lhe hand levers 70, 75, are inclined for- \vardly as shown so that the plow may be adjusted by :the tractor operator without lem ing his position, and the cord 53, by which the latch is operated, is also carried :to meonvenient position :Eorlmndlin by the operator. It will be understood t at for vthe :purpose of moving the plow from place ito place and turning the same about, the parts are brought to the position illustrated, and when the :furrow is to be turned the plow bottoms are dropped to the ground in the manner previously described and -permittedato enter the soil'untill their penetraition is limited by the stops as heretofore astated.
